Available options for specifying values of 'external' variables: Provide the value as a string:

-V / --ext-str <var>[=<val>]

If <val> is omitted, get from environment var <var>

--ext-str-file <var>=<file> Read the string from the file

Provide a value as Jsonnet code

--ext-code <var>[=<code>]

If <code> is omitted, get from environment var <var>

--ext-code-file <var>=<file> Read the code from the file

Available options for specifying values of 'top-level arguments': Provide the value as a string:

-A / --tla-str <var>[=<val>]

If <val> is omitted, get from environment var <var>

--tla-str-file <var>=<file> Read the string from the file

Provide a value as Jsonnet code

--tla-code <var>[=<code>]

If <code> is omitted, get from environment var <var>

--tla-code-file <var>=<file> Read the code from the file

Environment variables: JSONNET_PATH is a colon (semicolon on Windows) separated list of directories added in reverse order before the paths specified by --jpath (i.e. left-most wins) E.g. JSONNET_PATH=a:b jsonnet -J c -J d is equivalent to: JSONNET_PATH=d:c:a:b jsonnet jsonnet -J b -J a -J c -J d

In all cases: <filename> can be - (stdin) Multichar options are expanded e.g. -abc becomes -a -b -c. The -- option suppresses option processing for subsequent arguments. Note that since filenames and jsonnet programs can begin with -, it is advised to use -- if the argument is unknown, e.g. jsonnet -- "$FILENAME".
